In gymnastics,
tumbling, also known as
power tumbling, is an acrobatic sporting discipline which combines some of the skills of artistic gymnastics on the floor with those of
trampolining. It is practised on a 25-metre long spring track. It was developed from tumbling performances performed by
entertainers from very early times but as a sport is now codified, regulated, judged, and performed using standardised special acrobatic equipment.
